Hayami Kotono

An underclassman who transferred to the school the same time as the main character.
Her emotions are not easily read, and seems cold to the others. Her words are straightforward, and she calls her senpai by their names.
She fell in love with the protagonist after he saved her when she was lost in the school. She expresses her love bluntly and honestly, and resents anything she dislike. Her interest in sex made her very forward with the main character.
The MC joined the drama club, but more for the area where one could nap then any desire to be in a play.
